\"\"

\

Observe the graph:

\

The scale of the graph on the \"\"-axis is \"\" and \"\"-axis is \"\".

\

The line passes through the points are \"\" and \"\".

\

Find the rate of change.

\

\"\".

\

\"\"               (Formula for rate of change)

\

\"\"                (Substitute \"\" and \"\")

\

    \"\"                     (Subtract: \"\" and \"\")

\

    \"\"                          (Simplify)

\

Therefore, the rate of change of the graph is \"\".

\

\"\"

\

The rate of change of the graph is \"\".
